GATE.

SPECIFICATION forming part of Letters Patent No. 680,417, dated August 13, 1901. Application led April 11, 1901.- Serial No. 55,297.. (No model.)

T0 ctZZ whom it may concern:

Beit known that I, ISRAEL L. LANDIs,a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented new and usefullmprovements in Gates, of which the following is a specification.

. My invention relates to improvements in hinged swinging gateswhich are adjustable and are used in stock-yards, farms, meadows, fields, and about homes in city or town and for general purposes. It is adapted to be used on level ground or on hillsides, up or down. The whole gate may be raised high enough to pass snow-drifts orto let small stock pass under while it is closed for large stock. Either end may be raised or lowered while the other end remains up or down. I attain these objects by the construction as shown in thev accompanying drawings, in which- Figure l shows a face or front view of the gate A, hanging on the main post and latched to the front post; Fig. 2, a sectional enlarged view of the clamping device and guideplates cut through at the place where it is in position to secure the gate proper, A, to the slotted subpost D; Fig. 3, a sectional View of the clamping device used to secure the diagonal slotted sliding adjustable braces E to the horizontal rail a; Fig. 4, the cam-lever t' and bolt h, showing the cam open and the dotted lines showingitlocked or closed. Fig. 5 shows the friction-plate g with a central perforation and a roughened face, and also an end view of the same. Fig. 6 shows a modified form of the clamping-plates Z Z, in

` which they are wider at the place where they cover the slot in the subpost.

Similarletters refer to similar parts throughout.

The gate A is preferably made of wooden bars or rails a and the common upright battens B, bolted together by bolts or pins c, as in ordinary gates. On .the rear end of the gate is a subpost D,which is provided with a slot j at right angles to the gate, extending from its middle up and down a suitable distance to allow the raising and lowering of the gate. It isattached to the gate A at the rear uprights or battens B by means of bolts or nails c" and the clamping device shown in `slotf' in the brace E. Between this brace and the rail a is interposed the roughened friction-plate g, Fig. 5. This plate has a hole in the center', through which the bolt Zt/ passes and then goes through the batten B and the slotted braceE on the opposite side.

One end of this bolt h' has a nut and washer,"

and the other end a cam-lever t" and a washer,

by means of which these parts are rigidly,

The roughened friction-- clamped together. plate g prevents the brace E from slipping when the gate is adjusted and locked. If the `lever t" works too loosely, the nut on the bolt h may be tighened up to produce enough pressure or force on the clamp to hold the gate into adjusted position. quires to be raised or lowered, the cam-lever c" is released and the gate raised or lowered and secured or clamped by again turning down the lever Z., end of the gate can be instantly adjusted to prevent dragging of the gate and breaking it or to pass over snow or for hillsides or to pass small stock under it.

The clamping device, Fig. 2, above referred to, which secures the subpost D to the gate A, consists of two perforated guide-plates Z Z, secured to the rear uprights B B of the gate on opposite sides of the rear end of the gate at about the middle of the same and extending rearwardly and embracing the subpost D. The clamping-bolt h passes through these plates and through the slot f in subpost D. This bolt also passes through a coiled wire springn, interposed between these perforated plates Z Z, the ends of the spring resting against and forcing apart the plates Z Z, so that they may not bind against the subpost when the gate is raised or lowered,but that they may pass freely up or dow'n the same when the plates Z are released by opening the cam-lever If the gate re.

In this manner the frontv IOO . ted post in dotted lines o fu.

'L'. Around the springn on its outside and covering itis a loose hollow antifriction-roller fu, somewhat shorter than the coiled spring on its inside. This roller 'U works freely over the spring and serves to ease the raising or lowering of the gate on the subpost. This roller being shorter than the thickness of the snlipostD revolves freely always and does not interfere with binding the clampingplates ZZ to the subpost by means of the camlever i and bolt h when required. Now when it is desired to raise or lower the whole gate the locking cam-lever x' on the slotted braces E and that on the slotted subpost D are loosened, and the whole gate is freely adjustable. The rear end is then raised vor lowered to the desired height and locked by 1u rning down the cam-lever t'. Then the front end is raised or lowered, and the camlever z" there is also turned down and the gate thoroughly secured. The latch a: is a sliding wooden bar lying on the middle rail o. and passing between the front-end battens B and the second batten B and the plate Z. This plate is also provided with a cam-lever t' and bolt h, Fig. 4, or with a bolt and thumbnut, by which means the latch is securely held and locked, so that the latch and gate may not be opened by cattle rubbing against it or by the wind or by any other chance mishap opening it. Fig. 6 shows the plate Zwider at the rear part and two rollers r v in the slot- The bolt 72, and and the spring n in the slot of the subpost is the saine as shown in Fig. 2. The two small guide-plates marked K serve to steady the gate when the same is raised or lowered -at the rear end.

It is thus seen that the construction of my gate is quite simple. Its operation is easy. Its cost is cheap. Its desirable features of raising and lowering to prevent dragging and to let small stock pass under and prevent its breaking are firm and eifective. Its arrangementv t'or working up and down hillsides vor on level is perfect, so that it embraces about all these desirable features that are necessary in a gate for general purposes in a preeminent degree.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. In combination with the gate A provided with a subpost D slotted at right angles with the gate; the clamping-plates ZAZ secured to the gate by bolts c c", said plates embracing the subpost D; the bolt h, cani-lever t', spring n, roller/U secured through the plates Z Zand through the slotfin the snbpost; the diagonal slotted braces E provided with a cam-lever t" and bolt h and a friction-plate g interposed between the slotted brace and adjacent rail; the latch-bolt X and plate z secured with the bolt h and cam-lever i as and for the purpose set forth.

2. In a gate the clamping device consisting of two plates i Z secured to the rear uprights or batten B of the gate and embracing the slotted subpostD; the bolt h provided with cam-lever 11, spring n and roller n, passing through plates Z, and through the slot fof the subpost D, .in combination wit-h the diagonal slotted braces E the friction-plate g, the bolt h and lever t; to secure and adjust the slotted braces to the gate as and for'the purposes set forth.

3. In combination with a gate the perforated clamping-platesl l secured to the gate by bolts c c" and embracing the snbpost D, the bolt 72, passing through the plates Z Z through the slot f in the subpost D and through the spring n and the roller o; the slotted braces E secured by the cam-lever and bolt h at the lower front end of the gate, as and for the purposes described.

4. In combination with the gate A, the slotted subpost D, the clamping-plates ZZ, the bolt h, cam-lever t roller t, andthe braces E provided with bolt 71X, lever z" and frictionplate g as and for the purpose set forth.

5. In combination with the gate A the subpost D, the guide and clamp-plates Z Z secured to the battens B at the rear end of the gate, and embracing the subpost D, the bolt h passing through the plates Z, l, and through the slotf in the subpost D, the slotted braces E secured to the subpost D, and at the lower front end of the gate with a bolt h' and friction-plate g as and for the purpose set forth.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
